| 摘 要： | １ 中性昆虫的概念及田间动态１．１ 概念的提出吴进才等在对稻田节肢动物群落营养物种的系统调查中发现，稻田生态系中，既非害虫又非天敌的一类昆虫占整个节肢动物群落丰盛度的２０％～６５％［７，８］。生态学理论认为，系统中没有孤立存在的物种［１２］。数量庞大的这一昆虫类群在稻田生态系统中有何意义？与稻田害虫的发生有何联系？现有文献还少有涉及。吴进才等［７］、郭玉杰等［１］提出了中性昆虫的概念，用于指称传统植物保护学中的既非害虫又非天敌的一类昆虫，并就其田间动态及在食物网中的作用进行了系统调查、研究和讨论…

| Abstract: | The studies on neutral insects of agro-ecosystem in paddy field have been reviewed in this paper. The significance, role, and manipulating of neutral insects also have been discussed. Based on the effects of neutral insects on food-web of paddy field, the authors presented that we must pay more intensive attention to neutral insects and the effects of neutral insects on food-web must be taken into account in IPM of rice. |
